GASPUR'IFYING APPARATUS.

flB'e it known that L'Eansr Sci-murmur,

invented certain new and. useful Improvements in (las- Pnrifyingi Apparatus, oi which the following is a full, clear, and exact. descriptitm.

This inyention relates to purifying appa as illumior more. casings ha ving closed tapering; ends Within which l ouvers are provided where thegas enters and leaves each casing thus insuring the most uniform distribution of the gas possible'thro'uglunit the puritying mass. Gas admitted into such purifiers tends to im s by the mostjdirect route from tho louver at the gas inlet. which /possible or extends throughout the height of the purifier, to the louver at the gas outlet. As the purifying; material in the casing is in contact with all the inner walls of the casing which are not provided with louver-s, the gas is forced to traverse the whole purifying material.

It has been found that the purifying material is only in proper contact with the inner walls of the tower when the latter is first brought into operation, but that. after it has'been working a short time, owing to frittin and settling, spaces or clearances are formed both at the top of the purifier and at its lateral walls, so that the gas to be purified directly from inlet to outlet. Efficient working of the purifier is thus considerably hampered, as large quantities of es pass through the purifier without being purified, or a't'ter'having been purified only to an insullieient extent. According to this invention this drawback is obviated by pro viding between the louvers at the inlet and outlet of the gas, upright bal'llc plates which adjoin the upper and lateral walls of the casing and project into the purityiinr material in such a manner that they maize it imrender it very dillicult, for gas to pass direct from the inlet to the outlet,

even if there be clearances or free spaces between the walls oi. the tower and the purity lug material.

In the accompanying drawing, in which similar letters denote similar parts, 'Figure 1 is a vertical longitudinal section through the purifying apparatus. .Fig. 2 a cross section on line 2-2 of Fig. 1 and Fig. 3 a plan partly in cross section of Fig. l.

and taper-in" at their u per and lower ends, each tower lining provided at its upper end with a cover I) for tilting or charging, and with a removable bottom 1: for emptying or discharging the apparatus: In the. lower part oi. one side wall (Z which may be at rectangular cross section is arranged the gas inlet pipe 6, while the gas outlet pipe f is connected to the opposite side wall (2. The two side walls d are provided in the wellknown manner with louvers g by means of which the gas is distributed throturhout the enters and before escaping.

Between the two louversg is arranged an upright partition or battle plate theaipper portion /1- of which extends across the two towers (1,, u. and tits closely against the inner walls of theupper part of the towers, while the two end portions h h extend downward from the main battle it and are connected to the transverse walls '5 at right angles thereto. The battle 72, in, it, projects from the top of the tower below the lowest louver g, and from the transverse walls 11 a short distance into the purifying material as will be seen from the drawing. If the upper covers 6 of the purifier are arched, they must be provided with ribs is which, when the covers are closed, fit tightly against the upper edge of the battle.

If, after the charging of the purifier, fritting or settling of the purifying material takes place during working, no portion of the unpnritied. gas entering through the pipe 0 can pass direct to the outlet pipe f through the intervals or tree spaces which may have been formed, but all the impure gas is forced to flow around the baille h, 71,, 11- The gas has consequently to pass through the puritying material between the battle h, h and the outlet, whence it therefore issues in a purified state.

It will be understood that instead of the above mentioned partition or battle, several partitions arranged side by side in the puritier may be used if desired. These partitions must be upright so that they will not interfere with the automatic emptying of tho purifier when the bottom 0 is removed.

The portion h of the battle plate in the upper portion of the purifier can be separate from the lower portions 11,, 71. which are connected to the transverse walls i of the urifier, in which case these lower portions h must intersect the upper portion h in order prevent any direct assage of non-purified gas to the outlet t rough any gaps existing between the purifying material and the'walls of the tower.
